Environmental Impacts of Wind-Energy Projects (2007)

As wind energy development continues to expand, federal, state, and local agencies should adopt a consistent approach to evaluating the planning, regulation, and location of wind-energy projects. Although wind energy, which provided about 1% of U.S. electricity in 2006, is often considered an option for future energy development because it emits no atmospheric pollutants and is driven by a renewable source, other environmental factors need to be considered. For example, wind-energy facilities can have a negative impact on specific kinds of wildlife and whole ecosystems. In this report, the NRC proposes a framework that can help in evaluating tradeoffs between the benefits of new wind-energy projects and the risks of adverse environmental impacts before new facilities are constructed.

Battery electric vehicles have only a motor and battery, they recharge from the grid and their carbon emissions depend on the energy used to generate the electricity they use. Hybrid vehicles have both a gasoline engine and an electric motor, and use petroleum onboard when their batteries are exhausted. Some hybrid vehicles can charge from the grid and others cannot.

Sorry, that’s incorrect.
